[BF70x] RTC update timing during deep sleep mode

When BF70x is in deep sleep mode,

RTC time and date register still continuously is updating?


after wakeup, RTC register will be updated? 


At the customer site, DSP after come back from deep sleep mode,

immediately reading RTC register result is still kept the time when DSP went to deep sleep mode.

After 1 second later, reading RTC register result is updated with correct current clock time.


So I suppose during deep sleep mode, RTC still wake and keep clocking but no update register.



Thank you for your help as always.

Best regards,
